What is the output of the below code?
#include<stdio.h>
void main()
{
int var;
var = func();
printf("%d", var);
int var1 = 7;
var1 = func();
printf("%d", var1);
}
void func(void)
{
}
-----------------------------------------------------------
The above code tests a scenario where a function has been called and it doesn't return a value. But the calling function has assigned return value to variable. In this scenario, when function is not returning a value, the value assigned is not a valid and can be said garbage. This is the case with both scenarios where a variable has been initialized and a case where variable has not been initialized.
